Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

First, technical names or technical terms appearing in the embodiments of the present invention are explained as follows:

RT: a Render Target (Render Target), specifically a block of memory of a GPU (Graphics Processing Unit), for image caching to record rendering results.

Depth Buffer: a depth cache that holds the RT (distance of a scene element to the screen) of the depth information of the 3D scene rendering onto the screen.

Sampling: data is acquired from various RTs for calculation and the like, and sampling generates read-write operations (IO) of a CPU or a GPU, thereby generating bandwidth and power consumption.

Bandwidth: the bandwidth is an important index for performance evaluation, and in the rendering process, the bandwidth may refer to the number of times (data amount) of reading and writing the Depth Buffer and the Color Buffer, which may increase power consumption and heat generation of the mobile phone.

Screen Space Reflection algorithm (SSR for short): and simulating the reflection color at a certain position in the screen through the depth buffer and the color buffer. Repeated reading of the Depth Buffer is required to calculate the corresponding reflection position of a position on the screen.

Ray tracing and reflecting: a virtual ray is emitted from a virtual camera, the surface contacted by the ray and the direction of bounce are calculated in a 3D scene, and the finally obtained color is the reflection result.

A reflection probe: an image component placed in a 3D scene enters a direction and returns the color in that direction. It can be used to describe the scene around a location, and can also be used to simulate reflections, but with very low accuracy.

And (3) real-time rendering: mainly referring to rendering 3D scene data onto a 2D image. This image is usually referred to as a block of memory within the GPU. After rendering is completed, the engine copies the image data in the memory to the display for display.

Screen space technology: in general rendering techniques, different 2D images can be obtained by modifying scene data of a 3D space, but for some complex effects and optimizations, it needs to be achieved by screen space techniques. This technique requires rendering of a 2D depth image (depth map), a surface orientation information image (normal map), material information (material degree of metallization, roughness), and the like, in addition to rendering of the color of the 2D image. More complex effects can be made by using the series of 2D information, and the algorithm depends on repeatedly sampling various 2D information for operation, so that the dependence on the complexity of a 3D scene is reduced.

Projection matrix: a matrix that can project points in 3D space into 2D image space.

Common types of light reflection include: specular Reflection, ambient Reflection, light Reflection, and the like, in order to enable a user to have good game experience in a game, related technicians have proposed various light Reflection technologies in sequence, such as Reflection probe, specular rendering, ray tracing, Screen Space Reflection (SSR for short), and the like.

The reflection probe technology selects a simple color from a fixed image as a reflection result according to the direction of a point on the surface of a reflection object, and although the operation is simple and the equipment requirement is low in technical implementation, the flexibility is poor and the reflection precision is low.

The mirror rendering can be performed again under the water according to the position of the reflecting plane, so that a user can see an exquisite mirror reflection result, but the cost for re-rendering the scene model is too high, the requirement on equipment is high, and if the user does not prepare game equipment with strong performance, the user hardly has good game experience.

Ray tracing is an advanced real-time rendering technology, can accurately calculate reflection, refraction and scattering of all rays in a game scene, is not limited to rendering of a plane game scene, but has high requirements on the performance of equipment, and general high-performance equipment cannot well run ray tracing.

The screen space reflection algorithm is a post-processing technology based on screen space, and simulates the reflection color of a certain position in a screen through depth cache and color cache. The method does not depend on the complexity of the scene and the fixed cost overhead, has a good rendering effect, and is widely applied to different game devices such as a mobile terminal, a computer terminal and a host terminal.

Fig. 1 is a schematic diagram of a screen space reflection principle in the prior art, as shown in fig. 1, where a represents a virtual camera, which may refer to a view angle lens for acquiring a view angle of a user, and an image acquired by the virtual camera may be regarded as an image that can be observed by the user from a display screen; b represents a reflected object, and may refer to various game models in a game scene, such as an island, a ship, etc.; c represents a reflection plane, and may refer to a plane for reflecting a reflected object, such as a water surface, a mirror surface, etc.; n represents a reflected point; m represents a reflection point; d represents a normal line of the reflective screen at the reflection point; alpha represents the angle of incidence and the angle of reflection.

The principle of the screen space reflection algorithm is similar to that of observing a reflected object in a reflection plane by human eyes, a virtual camera is utilized to calculate a reflection direction according to a normal line and position information of a water surface, and multiple times of moving search is carried out along the reflection direction to determine whether a reflected object exists, namely, according to the positions of A, m and D in fig. 1, whether a point n exists is determined, if the point n does not exist, the visual angle of the virtual camera is continuously moved to a new position, the point m is searched again, then whether the point n exists is searched again according to A and the new point m, but each time the reflection position is changed, a system needs to resample Depth information and normal information once, read Depth Buffer to calculate the corresponding two-dimensional space position of the reflection position on a display screen of the device, and carry out one-time determination to determine whether the search is completed, so that a large number of repeated sampling and determination can cause the bandwidth utilization rate of the GPU to be too high to a great extent, resulting in a degradation of the performance of the device.

To enhance the player's gaming experience, in accordance with one embodiment of the present invention, an embodiment of a model rendering method is provided, it being noted that the steps illustrated in the flowchart of the figures may be performed in a computer system such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than presented herein.

It will be understood by those skilled in the art that the structure shown in fig. 2 is only an illustration, and does not limit the structure of the mobile terminal. For example, the mobile terminal may also include more or fewer components than shown in FIG. 2, or have a different configuration than shown in FIG. 2.

The model rendering method in one embodiment of the present disclosure may be executed on a local terminal device or a server. When the model rendering method is run on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system comprises the server and a client device.

In an optional embodiment, various cloud applications may be run under the cloud interaction system, for example: and (5) cloud games. Taking a cloud game as an example, the cloud game refers to a game mode based on cloud computing. In the cloud game operation mode, the game program operation main body and the game picture presentation main body are separated, the storage and the operation of the model rendering method are completed on the cloud game server, and the client device is used for receiving and sending data and presenting the game picture, for example, the client device can be a display device with a data transmission function close to a user side, such as a mobile terminal, a television, a computer, a palm computer and the like; but the cloud game server which performs information processing is a cloud.

In an optional implementation manner, taking a game as an example, the local terminal device stores a game program and is used for presenting a game screen. The local terminal device is used for interacting with the player through a graphical user interface, namely, a game program is downloaded and installed and operated through the electronic device conventionally. The manner in which the local terminal device provides the graphical user interface to the player may include a variety of ways, for example, it may be rendered for display on a display screen of the terminal or provided to the player through holographic projection. For example, the local terminal device may include a display screen for presenting a graphical user interface including a game screen and a processor for running the game, generating the graphical user interface, and controlling display of the graphical user interface on the display screen.

In a possible implementation manner, an embodiment of the present invention provides a model rendering method, which provides a graphical user interface through a terminal device, where the terminal device may be the aforementioned local terminal device, and may also be the aforementioned client device in a cloud interaction system. Fig. 3 is a flowchart illustrating a model rendering method according to an embodiment of the present invention, which proposes to provide a graphical user interface through a terminal device, where the content displayed by the graphical user interface at least includes: virtual scene, as shown in fig. 3, the method includes the following steps:

step S302, model data of a target model in a virtual scene is obtained.

Wherein, the partial submodel of the target model is positioned below the virtual plane, and the virtual plane is used for presenting the reflection effect.

The virtual scene can be a 3D game scene with light reflection; the target model may be a 3D model that is reflected, such as an iceberg, an island, etc.; the virtual plane may be a plane for reflecting light, such as a water surface, a mirror, etc.; the model data may be RT data of the target model in the virtual scene, including but not limited to normal data, depth data, color data, etc. of the target model in the virtual scene.

The virtual scene may be content displayed in a graphical user interface presented to the user through the terminal device, for example, a game image viewed by the user through a mobile phone screen or a computer display screen. The target model may intersect with the virtual plane, that is, the target model may be divided into two parts by the virtual plane, for easy understanding, the virtual plane is set as a horizontal plane, one part of the target model is located above the virtual plane, and the other part is located below the virtual plane, at this time, if the virtual camera is located above the virtual plane, the reflected part is the model part located above the virtual plane; if the virtual camera is located below the virtual plane, it is the portion of the model that is located below the virtual plane that is reflected.

It should be noted that the model rendering methods corresponding to the above two cases are the same, and for the convenience of understanding, the model rendering method when the virtual camera is located above the virtual plane is illustrated herein as an example.

In an alternative embodiment, after the virtual scene to be rendered in real time is determined, model data of the object model reflected in the scene may be obtained.

Step S304, based on the model data, first spatial data of a first point on the target model is determined.

Wherein the first point is a point on the sub-model on the target model that is located below the virtual plane.

The first point may be a point on the model portion located below the virtual plane; the first spatial data may be 3D world coordinates of the first point in the virtual scene.

In an alternative embodiment, after obtaining the model data of the target model, any point on the model portion below the virtual plane and the first spatial data corresponding to the point may be determined first.

Step S306, second space data of a second point on the target model is determined based on the first space data.

Wherein the second point is a point on the sub-model on the target model above the virtual plane.

The second point may be a point on the model portion located above the virtual plane; the second spatial data may be 3D world coordinates of the second point in the virtual scene.

It should be noted that the second point is not an arbitrary point, but is a point that is axisymmetric to the first point with respect to the virtual plane, that is, the 3D world coordinates of the second point can be determined from the 3D world coordinates of the first point and the coordinates of the virtual plane, and since the position of the virtual plane in the game scene is not changed in general, the virtual plane can be set to a plane whose vertical coordinates are 0 in order to improve the efficiency of determining the second spatial data. That is, after the first spatial data is acquired, the second spatial data of the second point can be quickly acquired from the first spatial data.

Step S308, determining the reflection color of the virtual plane based on the color information corresponding to the second spatial data.

The color information may be color data of a point corresponding to the second spatial data in the virtual scene, and the reflection color may be a color of a reflection point in a virtual plane displayed in the graphic user interface.

In an alternative embodiment, after the second spatial data is obtained, the reflection color may be determined according to the corresponding relationship between the second spatial data and the corresponding reflection point on the virtual plane, and a specific determination method is described below.

And step S310, rendering the virtual plane according to the reflection color.

In an alternative embodiment, after the reflection color is determined, the color of the reflection point corresponding to the second point on the virtual plane may be rendered according to the reflection color immediately, and when all the reflection colors are determined and rendered on the virtual plane, the formed image is the reflection image, and the user may view the reflection image through the virtual camera.

In at least some embodiments of the present invention, model data of a target model in a virtual scene is obtained; determining first spatial data for a first point on the target model based on the model data; determining second spatial data for a second point on the target model based on the first spatial data; determining the reflection color of the virtual plane based on the color information corresponding to the second spatial data; according to the method of rendering the virtual plane by the reflection color, the position of the first space data mapped to the graphic user interface is determined as the reflection position, the position of the second space data mapped to the graphic user interface is determined as the reflected position, then the color corresponding to the position is directly determined as the reflection color and rendered on the reflection position, the position color reflection color of the second space data mapped on the user interface is not required to be repeated for multiple times, and whether the second space data corresponds to the target model or not is not required to be repeatedly determined according to the reflection position, thereby avoiding the problem of large cost and expense caused by repeatedly sampling model data to determine the reflection position in the prior art, improving the efficiency of rendering the virtual plane, utilizing the color in the user interface to render the virtual plane, ensuring higher rendering effect and leading a user to obtain good vision, the game experience of the user is improved, and the technical problem that rendering precision and cost are difficult to balance when light reflection is rendered in real time in the prior art is solved.

In the above embodiments of the present invention, determining the first spatial data of the first point on the target model based on the model data comprises: determining original space data of a virtual camera in a virtual scene and target space data from the virtual camera to the lower left corner of a far clipping plane; determining first location data of a first point in a graphical user interface; the first spatial data is determined based on the original spatial data, the target spatial data, the first position data, and the original depth data in the model data.

The original spatial data may be 3D world coordinates of a virtual camera, and is expressed by CameraPosition, and the CameraPosition acquisition method may refer to relevant documents, which are not described herein again; the target space data may be X, Y, Z vector components of the virtual camera to far clipping plane lower left corner camera space; the first position data may be position coordinates of the first point mapped to a corresponding pixel point in the 2D image, and may be expressed in Texture [ u ] [ v ]; the raw depth data may be a distance of the target model from the virtual camera.

Since the virtual camera, the first point, and the corresponding reflection point on the virtual plane are on the same straight line, the first position data may be position coordinates of the reflection point.

In an optional embodiment, after the original spatial data, the target spatial data, the first position data, and the original depth data are obtained, the 3D world coordinate corresponding to the first point may be calculated based on a preset calculation formula of the first spatial data, where the calculation formula of the first space is generally used for the 3D world coordinate of the first point, and a specific calculation method is as shown below.

In the above embodiments of the present invention, determining the first spatial data based on the original spatial data, the target spatial data, the first position data, and the original depth data in the model data comprises: mapping the original depth data to a graphical user interface to obtain target depth data; obtaining a product of the target depth data and a first spatial component in the target spatial data to obtain a first product; obtaining a product of a second space component in the target space data and a first coordinate component in the target position coordinates to obtain a second product; obtaining a product of a third space component in the target space data and a second coordinate component in the target position coordinate to obtain a third product; and acquiring the sum of the original spatial data, the first product, the second product and the third product to obtain first spatial data.

The first spatial component may be the vector component Z; the second spatial component may be the vector component X; the first coordinate component may be an abscissa u of the first point mapped to a corresponding pixel point in the 2D image; the third spatial component may be the vector component Y; the second coordinate component generally refers to a vertical coordinate v of a corresponding pixel point in the 2D image mapped by the first point.

The first product may be a vertical coordinate value z corresponding to the first spatial data; the second product may be an abscissa value x corresponding to the first spatial data; the third product may be an ordinate value y corresponding to the first spatial data.

Since the process of presenting a graphical user interface to a user using a virtual camera is equivalent to the process of mapping a 3D virtual scene to a 2D image, the target depth data may be the result of mapping the original depth data in the 2D image.

In an optional embodiment, the mapping of the target model data from the 3D virtual scene to the graphical user interface is completed through a GPU rasterization process, that is, RT data such as depth data, color data, normal data, and the like of the target model in the 3D virtual scene may be obtained by performing mapping steps such as depth test, lighting calculation, coordinate transformation, and the like on the point, in order to distinguish the above different types of data, each type of data may be represented in the 2D image in the form of RGBA (Red-Green-Blue-Alpha) data, and a specific representation method and a mapping data relationship may refer to relevant documents, which is not described herein again. Alternatively, the mapped depth data image colors may be used to determine how far the target model is from the virtual camera, the farther the white representation is, the closer the black representation is.

That is, the above target depth data may be determined from the original depth data and the first position data according to the mapping step, and may be represented by DepthTexture [ u ] [ v ], representing the depth data of the target model at the first position coordinate Texture [ u ] [ v ].

After the target depth data is determined, the first spatial data, i.e. the 3D world coordinates of the first point with respect to the virtual camera, may be determined based on the target depth data, the target spatial data, the first position data and the raw spatial data.

The calculation formula of the vertical coordinate value z of the first spatial data is:

z＝DepthTexture[u][v]×Z+CameraPosition(z)；

the formula for calculating the abscissa value x of the first spatial data is:

x＝u*X+CameraPosition(x)；

the formula for calculating the ordinate value y of the first spatial data is:

y＝v*Y+CameraPosition(y)；

the final formula for the first spatial data WorldPosition is:

WorldPosition＝DepthTexture[u][v]*(Z)+u*X+v*Y+CameraPosition。

it should be noted that the above-mentioned use of different letters, phrases, etc. is only used as a short term, which is convenient for viewing a formula, for example, the CameraPosition represents the 3D world coordinate of the virtual camera, and the 3D world coordinate itself has no special meaning and is not limited specifically.

In the above embodiments of the present invention, determining second spatial data of a second point on the target model based on the first spatial data comprises: acquiring third spatial data of the virtual plane; based on the first spatial data and the third spatial data, second spatial data is determined.

The third spatial data may be 3D world coordinates where a virtual plane is located, for example, the virtual plane may be a horizontal plane with a vertical coordinate value of 0.

Fig. 4 is a schematic diagram for determining spatial coordinates according to an embodiment of the present invention, and fig. 4 is similar to fig. 3, except that a point o in fig. 4 is the first point, and a point n is the second point, i.e., the reflected point, and when data of a reflection point m on a virtual plane C is acquired by using a virtual camera a, it may directly acquire data of the point o on a target model B, and according to the principle of light reflection and the principle of triangle symmetry, it may be determined that the point n and the point o are symmetric about the virtual plane C. That is, the vertical distance from the first point o to the virtual plane may be directly obtained, and then the second spatial coordinate corresponding to the second point n may be directly determined according to the vertical distance and the third spatial data.

For example, if the first spatial data corresponding to the first point o is (3, 5, -8) and the virtual plane C is a horizontal plane with a vertical coordinate value of 0, it can be directly determined that the second spatial data corresponding to the second point n is (3, 5, 8).

In the above embodiment of the present invention, determining the reflection color of the virtual plane based on the color information corresponding to the second spatial data includes: mapping the second spatial data to a graphical user interface to obtain second position data; and acquiring color information corresponding to the second position data to obtain the reflection color.

In an optional embodiment, after the second spatial data is obtained, the second spatial data may be mapped to a pixel point in the graphical user interface according to the projection matrix, where a color corresponding to the pixel point is a reflection color, as in the implementation scheme of determining the first positional data according to the first spatial data.

The color displayed in the graphical user interface is used as the reflection color instead of the color of the target model corresponding to the second point, so that the problem that the determined reflection color is incorrect due to the fact that the second point is shielded by the target model can be effectively solved.

In the above embodiment of the present invention, mapping the second spatial data to the graphical user interface to obtain the second position data includes: acquiring a camera position of a virtual camera in a virtual scene, a first distance from the virtual camera to a far clipping surface, a second distance from the virtual camera to a near clipping surface and a view angle; determining a projection matrix based on the camera position, the first distance, the second distance, and the field of view angle; and obtaining a product of the second spatial data and the projection matrix to obtain second position data.

In an alternative embodiment, the projection matrix P is as follows:

wherein f represents the distance of the virtual camera to the far clipping plane; c represents the distance of the virtual camera to the near clipping plane; t-I represents the length of the graphical user interface; r represents the width of the graphical user interface.

After the projection matrix is determined, the second spatial data W may be directly multiplied by the projection matrix P to obtain the corresponding second position data H, where H is PW, that is, the coordinates of the pixel point in the graphical user interface.

In the above embodiment of the present invention, before obtaining model data of the object model in the virtual scene, the method further includes: determining first terrain data of the target model above the virtual plane and second terrain data of the target model below the virtual plane; and acquiring model data of the target model in the virtual scene in response to the difference between the first terrain data and the second terrain data being smaller than a preset threshold value.

The first terrain data may be terrain of a portion of the target model above the virtual plane near the virtual plane, such as a portion of an iceberg above the water surface; the second terrain data may be terrain below the virtual plane near a portion of the object model below the virtual plane, such as a portion of an iceberg below the surface of the water.

It should be noted that, in order to improve the efficiency of light reflection of the rendering model, the target model shown herein may be a model with consistent terrain trend and less deformation trend on the upper and lower virtual planes, such as icebergs, sand beaches, islands, etc., and for such target model, a smaller difference threshold H and a larger difference threshold I may be set. Optionally, after the first topographic data and the second topographic data are determined, a difference value between the first topographic data and the second topographic data is determined, and if the difference value is smaller than H, it is determined that the model may be rendered by directly obtaining model data by the method; if the difference value is larger than H but smaller than I, the target model can be adjusted in the game, and model data of the model are obtained for rendering after the adjustment is completed; if the difference value is greater than I, other rendering modes can be selected to render the model, for example, a screen space reflection algorithm is used.

Different rendering modes are set for different models, so that the model rendering precision can be better improved, and a user has better game experience.

Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (such as a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
